Weymouth resident Sue Kelly led “Dosie’s Team” for the fifth consecutive year in the 14th annual Samaritan 5K run/walk on Sept. 29.

Kelly has been involved with the Samaritans since her brother, Greg "Dosie" Dosenberg, committed suicide in 2002. Samaritans offer 24-hour hotline support and a befriending line, which was started in 1986 and is staffed by trained teenage volunteers.

Kelly was aware of her brother’s depression but she never knew what to do. She wrote a song for her brother just a few months before his death because she knew he was struggling, and has now posted it on YouTube.

In response to the video, viewers found Kelly’s FaceBook page and shared their stories of depression and suicide. Some of her friends even confessed their own depression and suicidal thoughts.
